Tauber-Solar

What Tauber-Solar does

Tauber-Solar is a German commercial and industrial (C&I) energy systems provider, headquartered in Tauberbischofsheim and operating through the legal entity TAUBER-SOLAR Holding GmbH with a subsidiary, Tauber Energy, focused on large-scale battery storage. The company delivers turnkey photovoltaic (PV) systems, commercial battery storage, and an in-house energy management system for businesses with high electricity demand, supported by planning/consulting, EPC/EPCM execution, monitoring and preventive maintenance, and repowering services. Financed via four managing directors (Klaus-Bruno Fleck, Zeno Fleck, David Fleck, and Arne Weinig) with apparent family ownership, the company claims 25+ years of industry experience, 100+ energy professionals, and 350+ completed C&I installations above 100 kWp.

The business operates a sales-led, enterprise field-sales go-to-market targeting German C&I customers in production, logistics, energy-intensive industries, and large commercial real estate. Revenue is generated through a mix of one-time EPC/EPCM project fees, hardware sales, and recurring streams including long-term O&M subscriptions, Power Purchase Agreements (PPA), contracting arrangements, and roof/surface leases; customers can also purchase systems outright. Project pricing is quote-based, with commercial PV installations typically priced at EUR 900–1,200 per kWp. A free, no-obligation potential analysis serves as the primary demand-generation CTA, supported by content marketing, LinkedIn/Instagram presence, and email newsletters.

In 2026 the company expanded by opening a new regional office in Munich to serve as a hub for South Germany C&I projects, and recruited experienced professionals from BayWa r.e. Power Solutions to strengthen project development and engineering capacity. The integrated offering—combining PV generation, battery storage with peak-shaving capability, and energy management across multiple financing models—positions the company as a one-stop-shop for C&I customers seeking to reduce exposure to volatile electricity prices, lower grid charges, and meet ESG reporting requirements.

Revenue model

1. EPC/EPCM — Engineering, Procurement & Construction: Tauber-Solar plans, designs, and implements photovoltaic and battery storage systems as a general contractor (EPC/EPCM) for commercial and industrial customers. Revenue is generated through one-time project fees for the turnkey delivery of PV and storage installations.
2. Operations & Maintenance (O&M): Ongoing monitoring, thermography, preventive maintenance, and servicing of installed PV and battery systems. Revenue is generated through long-term service contracts with commercial customers.
3. Power Purchase Agreement (PPA): Tauber-Solar finances and operates a PV installation on the customer's site; the customer purchases the generated electricity at a contracted rate lower than grid prices, without making their own capital investment.
4. Contracting: Tauber-Solar handles financing, installation, and ongoing operation of the PV system. The customer receives electricity at a fixed contractual rate. Revenue is generated through long-term electricity supply agreements.
5. Direct Investment / System Sale: Customers purchase PV and storage systems outright, maximizing their return on investment. Tauber-Solar supplies the complete turnkey system including planning, installation, and grid connection.
6. Roof/Surface Lease: Tauber-Solar leases unused roof surfaces or grid connection capacities from property owners to install PV systems, generating rental income for the landowner while Tauber-Solar operates the installation.

Core offering

Tauber-Solar plans, designs, and operates commercial and industrial (C&I) photovoltaic (PV) and battery energy storage systems as a turnkey EPC/EPCM contractor. The company delivers integrated energy solutions combining PV generation, battery storage, and intelligent energy management, with multiple financing options including Power Purchase Agreements (PPA), contracting, direct investment, and roof/surface leasing. Core services include planning and consulting, turnkey EPC implementation, ongoing monitoring and maintenance, and repowering of existing commercial PV assets.

Product overview

Tauber-Solar is a commercial and industrial (C&I) energy systems provider offering a comprehensive, integrated portfolio of PV, battery storage, and energy management products and services. The core offering consists of three integrated product pillars: (1) Photovoltaik für Unternehmen — commercial PV systems for rooftops and open areas; (2) Batteriespeicher für Unternehmen — commercial battery storage enabling peak shaving and self-consumption maximization; and (3) Energie­management — an intelligent energy management system that optimizes the interaction of generation, storage, and load consumption. These three products are underpinned and delivered through a suite of professional services including Planung & Beratung (engineering and advisory), Umsetzung EPC/EPCM (full turnkey project execution), Monitoring, Service & Wartung (ongoing operations and maintenance), Repowering (system modernization), and Finanzierungsmodelle (financing options such as PPA, contracting, and leasing). The company also offers advisory on Förder­möglichkeiten (government incentives and subsidies). Together, the products and services form a seamless, turnkey lifecycle offering from initial potential analysis through planning, construction, and long-term operational management.

Direct peers

• Enpal: Berlin-based solar leasing and PV installer primarily serving residential and small commercial customers in Germany with PPA-style financing. Competes with Tauber-Solar's PPA and contracting offerings and overlaps on integrated PV + battery solutions.
• Sonnen: Wildpoldsried-based German battery storage manufacturer and energy services provider (owned by Shell) serving residential and commercial customers with integrated PV + storage offerings. Directly comparable to Tauber-Solar's storage-plus-energy-management positioning.
• 1Komma5°: Hamburg-based energy services company offering integrated PV, battery storage, heat pumps, and EV charging to residential and commercial customers in Germany. Directly competes with Tauber-Solar in the German integrated energy-system segment with a similar one-stop-shop and financing-oriented model.
• Solarwatt: Dresden-based German manufacturer and installer of PV modules, glass-glass solar systems, and battery storage for residential and commercial customers. Comparable integrated PV + storage offering with overlapping German customer base.
• IBC Solar: German PV system integrator and EPC provider serving commercial, industrial, and utility-scale customers. Directly comparable to Tauber-Solar on C&I rooftop and ground-mounted PV EPC, with overlapping project sizes and customer segments.

Broad incumbents

• BayWa r.e. Large global German-headquartered renewable energy developer, EPC, and distributor active across solar, wind, and energy services. Overlaps with Tauber-Solar on C&I solar EPC at substantially larger scale — and notably the source of the talent Tauber-Solar recently recruited to staff its Munich office.
• E.ON: Major European utility with dedicated commercial and industrial energy-solutions offerings including on-site PV, storage, and energy management in Germany. Competes with Tauber-Solar for the same C&I decarbonization wallet, with broader portfolio and balance sheet.
• EnBW: Stuttgart-based German energy company with C&I solar, storage, and energy-management offerings, including turnkey solutions for industrial customers. A regional incumbent whose South German footprint overlaps with Tauber-Solar's Munich expansion area.

Emerging players

• Lichtblick: Hamburg-based German independent energy provider and energy-services company offering decentralized energy solutions, including PV and storage, for business customers. Comparable integrated energy-system play focused on German B2B customers.
• Zolar: Berlin-based German solar platform connecting customers with installers for PV and storage, with growing commercial offerings. Adjacent competitor with overlap on integrated PV + storage in the German market, though more platform-mediated than direct EPC.
